AIR CONDITIONING SYSTEM

摘要

An air conditioning system for eliminating uncomfortable feeling (draft feeling) produced when conditioned air strikes a human body directly, and ensuring comfortable feeling of heating. The air conditioning system (1) comprises an indoor heat exchanger (6) for radiating heat from supercritical refrigerant to air, and a fan (53) for generating an air stream to the indoor heat exchanger (6). At the indoor heat exchanger (6) at heat radiating, refrigerant is allowed to flow in a direction of approaching the upstream side from the downstream side in an air stream, and conditioned air heated at the indoor heat exchanger (6) is discharged upward to the room and is sucked from below. Discharge temperature of conditioned air is 45°C to 55°C, and conditioned air discharge velocity is up to 2m/s.
